[Scene: In the dead of night, before the mission, Yuki pays a visit to Shiro's room.]
Yuki: Shiro, can I talk to you for a moment?
Shiro: Yuki? What are you doing here?
Yuki: I couldn't sleep, and I wanted to make sure you're okay. I'm worried about you.
Shiro: I'm fine, Yuki. Don't worry about me.
Yuki: Shiro, can I ask you something? Why did you pretend to be weak when we were kids?
Shiro: (sighs) I didn't pretend, Yuki. I am weak. I only give small help to my teammates in the hero party. I don't contribute too much.
Yuki: (surprised) What are you talking about? You're one of the strongest people I know! You're the one who always protects everyone, even if it means putting yourself in danger.
Shiro: (shakes his head) That's not true, Yuki. I'm not as strong as you think. But I'll do my best on this mission to make sure I come back alive.
Yuki: (tears up) Please promise me you'll be careful. I don't want to lose you.
Shiro: (smiles) I promise, Yuki. I'll be careful.
Yuki: (hugs Shiro tightly) Thank you, Shiro. I don't know what I'd do without you.
Shiro: (hugs Yuki back) It's okay, Yuki. Everything will be alright.
Yuki: (wipes her tears) You know, if something ever happens to you, I don't know how I'll live without you.
Shiro: (serious) Yuki, if I die, promise me you'll keep living your life. That's my wish.
Yuki: (cries harder) Shiro, don't say that.
Shiro: (comforts Yuki) It's okay, Yuki. Everything will be alright. Now, let's get some sleep. We have a big day tomorrow.
[Scene: Yuki invites Shiro to sleep in her bed, hugging him tightly.]
Yuki: (snuggles closer to Shiro) I don't want to lose you, Shiro.
Shiro: (hugs Yuki) It won't happen, Yuki. I promise.
[Scene: The next morning, Shiro and the girls bid their farewells to the academy and set out on their mission.]
